Means of Transport
Transport systems like roads, railways, and airways facilitate the movement of goods and people, serving as the physical foundation of trade and economic growth.

Pipelines
A specialized network used across the country to transport crude oil, petroleum products, and natural gas directly from refineries and fields to factories and thermal power stations.
